SLOW Captions in Premiere Pro 15.0

[a.simon5]

Adding .mcc and .scc using the new Captions feature is slowing PP to a halt and make the program unusable until I close the sequence with the captions. This is true for existing projects/sequences (PP2020) with captions as well as newly-created projects & sequences with captions.

Downgrading back to 2020 for now. Anyone else experiencing this?

Sorry no reply. I am seeing this slowdown, but I have not pushed it yet. 

Mac or PC?

How long and/or demanding was your newly created try?
